Remedies/Causes
Playback order is determined when the files are
recorded.
This sometimes occurs while playing. This is
caused by how the tracks are recorded on the disc.
Insert a disc that contains MP3/WMA tracks.
This unit can only display letters (upper case),
numbers, and a limited number of symbols.
The track played back is not an MP3/WMA track.
Skip to another file. (Do not add the extension
code <.mp3> or <.wma> to non-MP3 or WMA
tracks.)
• Readout time varies depending on the USB
memory.
• Do not use too many hierarchy and folders.
• Turn off the power then on again.
Attach a USB memory that contains tracks
encoded in an appropriate format.
The track is unplayable.
• The attached USB memory may be
malfunctioning, or may not have been
formatted correctly. The files included in the
USB memory are corrupted.
• Do not pull out or attach the USB memory
repeatedly while "CHECK" appears on the
display.
This unit can only display letters (upper case),
numbers, and a limited number of symbols.
MP3/WMA tracks have not been properly copied
into the USB memory.
Copy the MP3/WMA track again into the USB
memory, and try again.
